Procedurally generated universe
The galaxy is created procedurally, delivering a variety of micro‑planets, asteroid belts and UFO encounters each playthrough.

Exploration is central, as you can fly to any planet you see, encountering diverse environments that support gathering and combat.
- Observe planetary features before landing to gauge resource types.

Ship parts and crafting system
Players collect resources to craft weapons, tools and upgrades, aiming to locate seven ship parts and ten blueprints. Over twenty possible upgrades can be discovered through this system. Crafting ties directly to exploration, as new parts often require materials found on distant worlds.
